Garbage can holders

ABSTRACT

Holders for plural refuse cans in which upstanding posts have opposed, hook-ended arms for engaging one of the usual carrying handles of a refuse can for canting the can angularly whereby opposed cans diverge upwardly; the hook arms substantially preventing rocking of the canted cans; and means to maintain a refuse can cover to the post; and in which the post is vehicular.

SELF-CLEANING TUBULAR SCREEN This invention relates to an improved form of self-cleaning screen for use in separating fluids from solid particulates. More specifically, this invention relates to a self-cleaning tubular screen formed by helically winding a wedge-shaped wire about a plurality of support rods and attaching same thereto in a manner to provide for radial outward flows. In other words, the cross-sectional area of the resulting continuous V-slot increases in the outward radial direction to give a self-cleaning effect when the flow of material initiates from the center of the tubular screen. The screen is susceptible to being rotated about its longitudinal axis so as to centrifugally force the material introduced into its interior, I radially outward. In a preferred form, the support rods may be spiralled so as to help effectuate longitudinal flow of the material introduced into the screen.

It is recognized that wedge-form separation screens are known and are used in various services such as well screens, vibrating or shaker screens, ore classifiers, and the like. Screens of tubular shape also have been used in a rotating action to centrifugally force a fluid'from slurry materials. However, it is to be noted that tubular screens of the self-cleaning type are generally fabricated to accommodate out-to-in flows. If an in-to-out flow screen is tobe manufactured, it is generally fabricated as an out-to-in flow screen and then reformed in a reverse manner in order to have the V-slot increase in an outward radial direction. This procedure is, of course, expensive and generally prohibitive.

It is thus a principle object of this invention to provide for an in-to-out flow tubular screen, suitable for rotation, having the benefit of a self-cleaning, but inexpensive construction. An alternative object, is to provide for an in-to-out flow screen construction that has support rod means that can aid in the positive movement of particulates in the longitudinal direction. 7 I

Broadly, this invention is a self-cleaning tubular screen comprising a plurality of spaced-apart longitudinal support rods and a wedge-shaped wire wound helically about said support rods and attached thereto, said wedge-shaped wire forming a resulting continuous V-slot of increasing cross-sectional area in the outward radial direction.

The means by which this type screen can be fabricated is generally known and is described in Johnson patents, US. Pat. Nos. 2,046,457; 2,046,458; 2,046,459; 2,046,460 and 2,046,461. Summarizing, these patents cover the apparatus and process whereby a wedge-shaped wire is helically wound about support rods and spot welded at each junction of wire and rod. The welding operation is described as an electrical resistance weld that fuses the two pieces together, the wire sinking into the rod some predetermined distance.

In most instances, the screen of this invention will be used for a flow or slurry of material to be directly introduced into the interior of the tubular screen. The fluid part of the slurry would be drawn off and thusly separated from solid particulates through the continuous slot by means of gravity, by means of maintaining a pressure differential between the interior and the exterior surfaces of the screen, or by means of rotational force; the particular means, however, not being a subject of this invention. In the simplest embodiment, the longitudinal flow of slurry is effectuated by maintaining the screen at a slope.

The solid particulates contained in the slurry of material are prevented from slogging in the continuous V-slot because the narrowest part of the V-slot is at the entry point on the interior periphery of the screen, and there is no depressed zone to permit particle bridging effects. Even in the event that a particulate would temporarily catch itself at one point of the slot, other particulates would tend to free it because of the continuity of the V-slot. v

A preferred embodiment makes use of the support rods as a means of establishing the flow of the particulates longitudinally through the screen. In other words, the support rods may be slightly spiralled so that when the screen is rotated, the

rods will drive the slurry of materials longitudinally forward. In an alternative application of this embodiment where rotation is not utilized, these spiralled support rods will enhance screening efficiency by changing initial longitudinal flow to circular flow, thereby increasing the contacted slot area. The resulting circular flow will also drive the fluid and finer materials through the slotted opening. In this embodiment, the preferred cross-sectional shape of each; of the support rods is substantially rectangular, thereby giving them a cross-sectional profile more likely to effect flow.

In this present invention, as previously noted, the novelty is in the winding of the wedge-shaped wire initially around the support rods to form the V-slot with a cross-sectional area increasing in the outward radial direction. However, the difficulty in obtaining such a result is manifested in the form of an at tachment of the wide face of the wedge-shaped wire to the support rods, as contrasted with the present conventional practice, which requires a weld to take place at the apex or smaller side of the wedge. If conventional wedge-shaped bars are used and a weld were to bemade at the wide part or base section of the wedge, the continuous feature of the resulting V-slot would be broken. Clogging would more likely take place, and any classification operations would be interferred with. Thus, preferably, a novel cross-sectional profile for the wedge-shaped wire is used as one means of fabricating the present in-to-out flow screen. This novel profile includes a ridge means along the central portion of the wide face of the wire, which may be used to assist in effectuating a weld to the longitudinal support rods; however, it is not intended to limit the ridge means to any one shape or cross section. Any shape chosen should be large enough to take a weld at the junction of a support rod and also have the dimensional requirements to prevent the weld from disturbing the edge of the wire.

The support rods will generally be equally spaced around the inner periphery of the tubular screen but may be spaced in any desirable manner. If the rods are not to be used to establish longitudinal flow through the screen, most probably they will be made parallel to the longitudinal axis of the screen. Also, the cross-sectional profile of the support rods may be of most any shape but consideration must be made in order to facilitate a strong weld. Round, oval, square, rectangular and all possible combinations may be considered probable cross-sectional profiles. In choosing a proper shape, the overall strength of the screen must be taken into account, in addition to the strength of the weld.

When the support rods are used as means of establishing flow, consideration must also be given to the area exposed to the particulate flow. It is for this reason that the dimension of the inner and outer sides of the cross-sectional area of the support rods will generally be made smaller than the dimension of the two adjacent sides. Again consideration must be given to the strength of weld and to the overall strength of the screen in establishing a proper cross-sectional profile.

A] 7 22 Ste ATTOR/[IEYS GARBAGE CAN HOLDERS My invention relates to garbage can holders, the present application being a continuation-in-part of copending application Ser. No. 598,993, filed Dec. 5, 1966 now abandoned.

Garbage cans are usually placed in back of buildings or behind lawn fences and are often tipped over or knocked down by passing children or dogs in search of food. The lid of a fallen garbage can is easily dislodged in such event and the contents of the can strewn over the ground, presenting an unsightly and unsanitary condition. Also, garbage cans standing on the ground often become wet or slimy underneath from rain or sprinkling of lawns, and rust out, shortening their period of usefulness. In view of these disadvantages, it is one object of the present invention to provide means for supporting garbage cans off the ground and in a position where they cannot be upset or knocked down.

A further object is to design a support of the above character which holds garbage cans in a manner to yield laterally and at a receding angle, so that the paws of an animal will slide off a can when attempting to engage or knock the same over.

Another object is to provide a support in the nature of a center post suitable for suspending a garbage can on each side, rotatable to bring either can into handy reach for purposes of filling or removal, and secured in a permanent base against removal or theft.

An additional object is to construct the center post of the holder with means to support the upper part of each can from the handle on the inner side thereof, while the post itself serves as a lateral support for the cans at the bottom.

A further object is to extend tie means from the center post to the lids of the cans supported by the same, and also provide retaining means for the lids at the top of the center post when they are removed from the cans in order to allow the same to be filled or emptied.

A further object is to provide a wheeled support for the garbage can holder and means to draw it to a location where the handling, removing or emptying of the garbage cans may be more convenient.

Another object is to provide a garbage can holder which is wheeled at the rear and receives a handle as a frontal support,

the lifting and drawing of the handle propelling the holder in forward direction if it is to be moved to a different location.

A still further object is to extend a tongue in forward direction from a rear wheel axle forming part of the holder, and support a center post of the same at a point spaced forwardly from the axle in order that the weight of the cans may not tilt the holder rearwardly and upset it.

A better understanding of the invention may be gained by reference to the accompanying drawings, in which:

FIG. 1 is an elevation of the improved garbage can holder, partly broken away; a

FIG. 2 is a fragmental duplication of the holder showing one garbage can removed and its lid taken off and secured in an out-ofthe-way position at the top of the holder;

FIG. 3 is a plan view of the lid as seen in FIG. 2, partly broken away;

FIG. 4 shows end fragments of a crossbar situated near the top of FIG. 1, partly in section and on a larger scale;

FIG. 5 is an enlarged section on the line 5-5 of FIG. 1;

FIG. 6 is an enlarged plan view of a crossbar seen at the top of FIG. 1;

FIG. 7 is a perspective view of the improved holder with the can covers closed;

FIG. 8 is an enlarged elevation of the top left-hand portion of FIG. 7, showing the cover in that region raised off the can and hung on a temporary support;

FIG. 9 is a section of the central portion of FIG. 8, taken on the line 9-9 of that FIG.; and

FIG. 10 shows a fragment of the holder post modified to receive a ground-engaging center rod instead of the wheeled support.

. mounted on opposite sides thereof are indicated at 11. The

tubular construction and indicated at 10; and the garbage cans cans are supported by a sidebar-providing frame 13 situation between them and receiving the post 10 in the middle; and the side bars of the frame are secured to the post by welds 13a. The side bars terminate with upward hooks 13b and cross pins 13c suitable for impaling the handles 11a projecting from the inner sides of the cans 11 as seen in FIG. I. The cans are thus suspended with an inward slant, and receive lateral support at the bottom from the post; FIG. 2 shows one can raised off the related hook 13b.

In order to bring either garbage can 11 within handy reach for filling, or removal from the related hook 13b, the center post is swiveled in a base 15; the latter is of heavy metal and set in a concrete ground foundation 16. While any suitable method for swiveling the post may be employed, the one shown uses a stub shaft 18 rising from the base 15 into the center post and formed with an annular groove 18a; and the bottom of the center post is reinforced by an external collar 10a, and carries a pin 10b directed freely into the groove 18a.

Tie means are provided for the lids 20 of the garbage cans to render them handy and prevent their loss. Thus, FIG. 1 shows a horizontal crossbar 22 welded at 22a to the center post, the crossbar being tubular for receiving one of the end portions of a pair of coil springs 23 in the ends of the crossbar; and such end portions are welded to the crossbar as indicated at 23a in FIG. 4. Each lid 20 is made with a conventional handle 20a; and for the present purpose a short tube 25 is welded at 25a to the handle. It is noted that the supporting frame 13, the crossbar 22, the lid handle 20a and the tubes 25 are all in alignment; and the outer end portions of the coil springs 23 are fitted into the inner ends of the tubes 25 and welded to them,

in the same manner as the inner ends are connected to the crossbar 22. The springs therefore serve as flexible and yieldable attaching means for the lids 20.

When either lid 20 is removed, the invention makes provision for its temporary support in a handy place. Thus, the top of the center post receives a crossbar 27 whose middle part is welded to the post as indicated at27a. The end-portions of the crossbar 27 are bent on the same side thereof to form hooks 27b facing each other, as seen in FIG. 6. FIG. 2 shows that the left-hand lid 20 has been inverted, and its handle 20a linked into the left-hand hook 27b of the crossbar 27 to form a retentive support for the lid.

It will now be apparent that the invention has a number of advantageous features. Thus, the center post is a fixture erected on a permanent base and constituted to support a pair of garbage cans in compact and balanced relation. Further the center post is swiveled to allow either can to be moved close for filling or removal. Further, the cans are mainly supported by anchoring their inner handles he where the cans will tilt and bear at the bottom against the center post, the lateral yieldability of the cans and their receding positions making it impossible for animals to secure a hold on either can with intent to upset it. Further, the cans are suspended well of the ground, so that they will be dry on the bottom and serve without deterioration over a long period of use. Further, means are provided to keep the can lids tied to the center post whether on or off the cans, and to be mounted out of the way when taken off the cans. Finally, the novel holder is made up of few and sturdy parts, and serves to maintain the garbage cans in a stable and sanitary condition.

As will be appreciated from examination of FIG. 5 of the drawings, the spacement of the hook-providing side bars of the frame 13 is such that the outer surfaces of the hooks 13b will be closely adjacent to the ends of the can handles Ila. This is important because it keeps the cans 11 from shaking and wobbling laterally in the wind. The cross pins 13c of FIG. 5 are also important in that they reinforce and perpetuate the spacement of the side bars of said frame 13.

DESCRIPTION FIGS. 7- 10 Except as hereinafter noted, the FIGS. 7- l and FIGS. 1- 6 forms of the invention are the same, and identical parts in FIGS. 7-10 are designated by the FIGS. l6 reference characters. Corresponding, but structurally slightly different FIGS. 7 110 parts, are indicated by the earlier used reference character followed by x.

Thus, in FIGS. 7l0 the tubular post is 10x and a shaft 118x (FIG. 7) may replace stub shaft 18 of FIG. l; and also the coil springs of FIGS. 7 and 8 are 23):, their lid-carried securing tubes 25x; and the tubular post-carried crossbars which secure the other spring (23x) ends are 22.x.

The means for mounting the can covers of FIGS. 7l0 in overhead out-of-the-way position of FIG. 8 comprises in each instance, a wire rod 38 having a foot 38a welded to the crossbar 22x, each rod 38 rising slantwise in outward direction to terminate with a side hook 33b (see FIG. 9). FIGS. 8 and 9 show the inner end of the can cover handle 200 as engaged by the hook 38b; and the heavier outer portion of the cover 20 pivots by its weight from the hook 38b to prevent inner post direction creeping of the cover over the related rod 38. This is an important point, as will be appreciated.

As shown, the wheeled can holder, or support, of FIG. 7 provides the wheel-ended rear axle 30 having the forwardly extending tongue 32. An upstanding functional integral pivot rt d 18x rises from the tongue 32 forwardly of axle 30 and into the tubular post 10x to support it at its closed top as indicated in FIG. 7; 30a indicates the axle-carried wheels. Placing the weight of the post 10:: and supported cans l 1 forwardly of the axle 30 prevents the assembly from tilting backwards and upsetting the eans. The post can be rotated for nearest access to either of the garbage cans l I illustrated.

The rolling post 10x support or carrier, has its tongue 32 provided with a long upstanding handle 35 having an upper hand grip 35a. The front end of the tongue 32 is forked as in dicated at 32a, to make a pivoting connection 32b with the handle above its foot (35b) providing bottom portion. Such foot portion 35b therefore serves as front-end support for the can-carried tongue 32 when the carrier is stationary, and maintains the center post Mix in a vertical position. However, if it is desired to move the can carrier or holder to a different place for more convenience, it is only necessary to draw upwardly on the handle 35, this imparting a slight rearward tilt to the tongue 32 and post 10x, as indicated by finely-dotted lines in FIG. 1. Now the foot 35b of the handle 35 is free from ground engagement, and it is an easy matter to draw the carrier or holder forwardly by means of the handle 35.

In case a wheeled support is not desired for the tubular post Mix, a modification of the post-pivoting rod 13. is indicated at 18w in FIG. 10 as a rod with a spike end my to be embedded in the grounds shown in FIG. 10.

Regarding the FIGS. 7l0 form of invention, it will be apparent that the improvements described lend the garbage can holder greater efficiency. Thus, the center post llllx is made shorter by eliminating the top bar 27 of the FIGS. 1 and 2. Instead, a pair of simple wire rods 38 attached to the main crossbar 22x suffice to suspend the can covers 20 in the overhead positions of FIGS. 7 and 8. Further, a major improvement lends the can holder mobility by the use of a carriage with a single wheeled axle 30 and a tongue 32 extended from the same in forward direction. In front a simple handle 35 serves either to station the carriage against self-rolling movement or raise the same slightly for forward hand propulsion. The center post 10x assembly also exerts its weight on the carriage to keep it in place, and bears on the handle pivot 32b to normally maintain the foot 35b of the handle in ground engagement. Further, offsetting the center post Mix in forward direction from the axle 30 imposes sufficient weight on the tongue 32 to keep the center post 181: from tilting rearwardly and upsetting the cans 11 when the handle is raised to propel the holder by hand. The improved holder therefore has the advantages of efficiency, few and simple parts, and convenience in use.
